Patented-Jul 22, 1930 UNITED STATES (PATENT-OFFICE I CLYDE L. WHITE, on'roLEDo, oHIo, AssIeNon'ro THE WiLLYS-OVERLAND COMPANY,

or TOLEDO, OHIO, A CORPORATION on OHIO i BRAKE-BAND SUPPORT Application filed May 31 My invention relates to brake mechanisms for automobiles and 1t has particular relation to transmission brake mountings.

One of the ob ects of the invention is to provide a brake mounting which will maintain the band in a posltlon apart from the drum 1 while the brake is released, and also to'provide a construction in which the brake band is positively maintained in aligned relation with respect to the drum.

Another object of the invention is to provide a simplified brake mounting which may be constructed at a reduced cost and may be repaired with fewer operations than is possi- 1' ble with brakes of present day design.

ient means for withdrawing the band from engagement with thedruin while released and having a-more extended efiective sphere of operation than is possible by other singlespring brake releasing mechanism.

To attain the aforementioned objects, an embodiment of the present lnventlon may in:

clude a brake drum and band of conventional design which are slidably associated, with guiding means that are adapted to withstand torsional forces incident to the braking action. A leaf spring member of arcuate contour disposed adjacent the band is resiliently.

supported near its mid-portion by a suitable band at spaced points. The spring serves to "prevent the brake band from riding or drag= ging on the drumwhile the brake is in a released position. 7 a a v Additional objectsof invention and a a rectangular member 18 which isrigidly secured to a su table ad o1n1ngmember, such 'for'example, as the transm ssion, (not shown).

dhe brake combination includes a drum 9 surrounded by a metallic strap 10to which there isriveted a brake lining 11 of suitable texture and Whichis provided at each end with an aperture 12 and 13, adapted to be securedto a brake arm (not shown), preferably of the so-called floating pivot design. Ata

point removed from the extremities of the strap a pair of U-shaped guide elements 14 are rigidly secured. Each of the guide memhers is riveted at its base portion to' the strap. The outer up-turned ends'are each provided with a slot 16whereas the adjacent Lip-turned ends are reinforced by means ,of an in denture l7 and serve as guides, thatslidably engage I The member 18 is provided with a tapped "aperture wherein-a set screw 19 having ailock nut 21 is fitted. The positionof thescrew defines one limit of movement of the band which is abutted thereagainst. Aleaf spring'22 hava ing upturned ends which fit in the slots 16 of the guide members and having an apeiture23 in its mid-portion that fits over the projected port on of the set screw, is maintained in her which has an extended sphere of in fluenceby' reason of spaced pointsof engagecausing a sliding movmentbetween the guide members 14 and the rectangular'member 18. At thesame time the band'will have atendreacting forcesof the spring, v I will be noted fl that the present invention includes 1a, simplified, i inexpensive: brake mounting ,construetion in which the movement of theband is restrictg d and guided,

in which. the general;operation isjim- I proyed. -It will further be noted that: the construction obviates the "necessity 10f afcoil spring and ancillary structural elements, and.

.cy to be spread outwardly by reason of the V 'ment with; the band,raises the-same radially supporting member, and 1s secured to the affords a compactness such as is demanded in present day automobile design.

Although there is illustrated but a single embodiment of the invention, the principles underlying the same are not so limited, but as Will'be apparent to those skilled in the art, may be extended to include other modifications Without departing from its scope,

Wherefore I desire that it be limited only as 'indic'ate'd'in the appended claims. I

I claim: 1. The combination of a brake drum, a brake band adapted to engage the outer surface thereof, means restricting one portion 1 of the band to movement radially of the drum,

an elongated leaf spring secured to the restricting means and the brake drum for raising the band free of the d rum, and said spring being positioned substantially parallel to the brake band. 7

2. The combination; of a brake drum, a

. brake band adapted to engage the outer surface thereof, means restricting one portion of v i the band to movement radially of the drum, an elongatedresilient member secured intermediate its extremities to the restricting means and joinedadjacent its extremities to the ban said resilient means being adapted to raise the band free'of the drum.

The, combination'of a brake drum, a band adaptedto engage theouter surface thereof, radially projected spaced members rigidly secured to the outer surface ofthe band, supporting means slidably disposed between the projected members, and an elongated resilient member 'securedintermediate its extremities to the supporting means, and i joined adjacent its extremities to the'band whereby it raises the band free of the drum.

4. The combination of ar brake drum, a band adapted toengage the outer surface thereof, radially projected spacedmembers rigidly secured to the outer surface of the band,a band supporting member slidably disposed between the projected members, means adjustably secured to the supporting member and projected therethrough adapted to engage the band and limit the movement thereof, and an elongated resilientmember secured at its midrportion to the supporting means and operatively' disposed at its extremities With the bandwherebyitr ises the band freeof the drum.
